Glan Laser Polarizers

March 8, 2021
Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction.

  Glan Laser Prism Polarizer consists of two identical prisms made from birefringent materials, the prisms are assembled with an air gap in between. This polarizer is a modification of the Glan Taylor Polarizer and is designed to induce less reflection loss at the prisms’ interface. The versions that are mounted with two escape windows allow rejected beams to escape out of the polarizers, which makes the polarizers more capable of handling high energy laser systems.

Hangzhou Shalom EO offers glan laser polarizing prisms made of Alpha-BBO (wavelength range 200-300nm, 300-700nm, and 700-3500nm), Calcite (wavelength range 350-2300nm), YVO4 (wavelength range 500-4000nm). The polarizers are of a high extinction ratio (<5x10^-6),  mounting options of either round or rectangular shapes are available and could be configured with escape windows.


  • Stocked and custom modules available
  • Three material options: Alpha-BBO, Calcite or YVO4
  • Angle of cut close to the Brewster’s angle
  • Air-spaced construction and short dimensional length
  • High Polarization Purity and Wide Wavelength Range
  • High extinction ratio (<5x10^-6)
  • Mounting Options: Rectangular or Round, and could be configured with escape windows.
